Meta Platforms has revealed new details on how it plans to integrate third-party messaging into its popular platforms, WhatsApp and Messenger, in response to strict new European Union regulations. The Digital Markets Act (DMA), which aims to curb the dominance of major tech companies, is pushing Meta to open its messaging services to external apps—making cross-platform communication a reality for users in the region.
This move marks a significant change in how Meta’s messaging platforms operate. Historically, platforms like WhatsApp and Messenger have maintained walled gardens, allowing only users of the same service to interact. However, the EU’s new laws now demand that companies like Meta provide interoperability, which will allow users to communicate seamlessly across different apps.
What Users Can Expect
The integration of third-party services will be rolled out in stages. Meta has announced that users in the European Union will begin receiving in-app notifications once the feature becomes available, allowing them to store and manage conversations from multiple messaging apps within WhatsApp and Messenger. In this way, users won’t need to switch between apps to stay in touch with friends or colleagues using different services.
While initially limited to core functions such as basic text exchanges, Meta is already preparing to roll out additional features that mirror the familiar user experience of WhatsApp and Messenger. These features include sending reactions, direct replies, typing indicators, and read receipts—ensuring that cross-app conversations maintain the same functionality as native chats. In fact, Meta has stated that its team is “going beyond” the minimal requirements laid out by the EU, working to enrich the user experience when integrating third-party services.
A Step Toward Cross-App Group Chats and Calls
The changes don’t stop at individual messaging. Meta has ambitious plans to integrate more complex functionalities, including group chats with users on third-party platforms. By 2027, Meta aims to introduce audio and video calling between different messaging apps, taking interoperability to a new level. This move will allow users to not only chat but also connect via voice and video, making WhatsApp and Messenger even more powerful hubs for communication across the digital ecosystem.
However, some details remain under wraps. Meta has yet to provide full specifics on how this system will work technically or which third-party messaging apps will be supported. What’s clear, though, is that this interoperability push signals a profound shift in the messaging landscape—one driven by legislative pressures rather than market forces.
How EU Laws Are Shaping Tech Giants’ Moves
At the heart of these sweeping changes is the European Union’s Digital Markets Act, a set of regulations designed to promote competition and limit the monopolistic power of Big Tech. The law requires that “gatekeepers” like Meta, with their vast user bases and entrenched ecosystems, open their services to third-party developers. WhatsApp, with its 2 billion users globally, and Messenger, with nearly a billion, are among the most prominent platforms affected by these rules.
For Meta, this represents both a challenge and an opportunity. On one hand, the company is being forced to loosen its control over user data and communications—a significant shift from its previous strategy of keeping its services closed off to competitors. On the other hand, by implementing these changes effectively, Meta could lead the charge in a new era of interconnected, cross-platform communication, setting the standard for the industry and gaining a competitive edge in complying with these emerging regulations.
A More Connected Future or a Security Nightmare?
While Meta’s embrace of third-party messaging could greatly benefit users by simplifying communication, it also raises questions around privacy and security. WhatsApp, in particular, is known for its end-to-end encryption—a feature that has been central to its appeal. The question remains whether this level of security will be maintained when integrating with external apps, some of which may not offer the same rigorous protections. Meta will need to tread carefully to ensure that it maintains the privacy standards users expect, even as it opens up its platforms to the wider digital ecosystem.
For now, Meta has reassured users that it will continue to prioritize privacy and security. It’s likely that more detailed information will emerge closer to the rollout of these features, particularly when it comes to encryption and data sharing between different platforms.
The Road Ahead
As the world’s largest messaging platform prepares to evolve under pressure from EU regulations, the broader question is whether these changes will catch on globally. While the new features are being introduced initially in Europe, Meta may well extend them to other regions, depending on how the market reacts and the legal frameworks in place.
In the meantime, users across the EU can look forward to a future where their messaging apps are less siloed, allowing for easier communication across platforms. Whether you use WhatsApp, Messenger, or another service entirely, Meta’s upcoming updates promise a more connected and seamless experience—one that could change the way we think about messaging forever.
Meta’s efforts to comply with the EU’s demands are already setting the stage for a new era in digital communication. Whether it’s group chats, voice and video calls, or cross-app conversations, the integration of third-party messaging represents a giant leap forward for the platform—one that could reshape the messaging landscape for years to come.
